Abstract
THE lecture opens with a brief reference to the researches of Leslie, Rumford, and Melloni. The labours of Tyndall and Magnus, as far as they bear upon the present subject, are then succinctly sketched, their points of difference being signalised and briefly discussed. This preliminary sketch is wound up by a reference to a recently published paper by Lecher and Pernter, who, while supporting the lecturer in the matter of gases, dissent from him in the matter of vapours. These investigators are especially emphatic in affirming the neutrality of aqueous vapour to radiant heat. Following Magnus, they refer Tyndall's results to what: Magnus calls “vapour-hesion,”that is to say, to the condensation of the vapours on the surfaces of the plates of rock-salt used to close the experimental tube, and on the interior surface of the tube itself.
